Not All SDWAN Members appear in static routing table

Hi,

We have created the SD-WAN and has 4 members.

We also create default route with sdwan enable.

When we 'get router info routing-table static', it only shows 3 SDWAN members.

Why does the static routing table only have 3 SDWAN members?

Hello,

First, check this:

#get router info routing-table database

This will show you if route was at least created and maybe just SDWAN is disabling it.

Then, check health-checks. Check if health-check that has Tun-A-M1 is up or down. If health-check is down, it might remove route.

Hi,

The 'get router info routing-table database' also shows only 3 Tun.

Then, the health check shows that Tun-A-M1 is up.

So why does the Tun-A-M1 not appear in the routing table?

Hi,

What FortiOS are you running? Can you check this setting, maybe you have non-default value:

Firewall (root) # show full system setting | grep ecmp
    set ecmp-max-paths 255

Hi,

We are running v6.4.10

The ECMP max value is 255.

Hi, at the moment, only thing that I can suggest is to delete default route and re-create it (if you did not do it yet). Also, can you share configuration for that static route?

Hi,

Here is the static route configuration.

Hi, and recreating the route does not resolve it, right? I don't have anything else to check atm, because next thing I would be just checking VPN configs, IPs, kernel table, etc. Feel free to open TAC ticket.

Hi,

We tried to recreate the route and it solves.

Also, when the FortiGate is rebooted, it also solves.

 

Thanks
